This motion detector (PIR) can be used to switch on lights outdoors and indoors (IP44). Works best outdoors, but also in areas where people usually just pop in and out, such as cloakrooms, porches, storage rooms, technical rooms, etc. Wall mounting is preferred, but ceiling mounting is also possible. The PIR sensor switches the lights on when it detects movement in the beam area and switches the lights off after a certain time after the last detected movement. The on-time is adjustable between 10 seconds and 7 minutes. The detector is black and is suitable for installation on dark surfaces.
Motion detection is done by infrared, which works in such a way that when the sensor detects an abnormal temperature (heat) in the range of the beam, it turns on the lights. We do not recommend installation near an air conditioner, air source heat pump or radiator, as heat variation against other backgrounds will cause the lights to turn on.
The motion sensor also includes a twilight sensor, which makes this a good choice for outdoor pathway lights and night lighting, turning on the lights from motion only when the twilight level is at a certain level. So, for example, certain outdoor lights will come on when motion is detected, but only at dusk. The light level can be adjusted from a near dark level of 3 lx to a full bright level of 2000 lx.

WHAT IS CRI, THE COLOUR RENDERING INDEX
High quality LED lights also have a high colour rendering index, or CRI. A good colour rendering index (CRI) for home use is above 90, and nowadays many market lights are unfortunately closer to 80.
CRI tells you how well an LED light displays colours as they should be. For designers and architects, as well as interior designers, it should be one of the most important considerations. Make sure the lighting is perfect so that your artwork is what it is meant to be.
Colour rendering index
The colour rendering index is expressed as a number on a scale from zero to 100, where 0 = no colour rendering and 100 = full colour rendering. The colour rendering index of LED lights is also known as Ra, which is measured on a smaller scale than CRI. This Ra value does not include red tones or skin tones, for example, so it is a 'glossed' figure for the true quality of an LED light.
RA value
The Ra value measures the reproduction of colours using eight different reference colours. CRI takes into account the wider (15) wavelength range, including reds and other warm colours.
The Ra value is calculated by cutting the wavelength range, weighting the blue and violet tones, and calculating the weighted average of R numbers 1-8.
Excluded from the Ra value are, for example, the colour rendering of bright reds, yellows and greens, and shades close to skin tone. These are described by R-values between 9 and 15. The following is a picture of a measurement result that easily confuses the consumer.
This measurement is from a 9W CCT Led spot
